USN-6033-1: Linux kernel (OEM) vulnerabilities
USN-6033-1: Linux kernel (OEM) vulnerabilities It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. (CVE-2023-1829) William Zhao discovered that the Traffic Control (TC) subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2022-4269) Thadeu Cascardo discovered that the io_uring subsystem contained a double- free vulnerability in certain memory allocation error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-1032) It was discovered that the TUN/TAP driver in the Linux kernel [ more… ]
